IKO CRY26VUU Inch Roller Follower, 7/16 in bore, 1 5/8 in OD, Sealed, Cylindrical
Available
This page covers 18 IKO CRY Series inch non-separable roller followers (track rollers) (CRY12VUU to CRY64VUU, 1/4 to 1 1/4 in bore): full complement needle rollers, sealed type construction and a cylindrical outer ring. Choose the size in the options above; each variant has its own dimensions and ratings in the Model Details.
The CRY series is the inch series non-separable roller follower: a full complement type with a black oxide surface treatment, with side plates fixed on both sides of the inner ring. A roller follower (track roller) is a bearing designed for outer ring rotation, with rollers inside a thick-walled outer ring. The outer ring runs directly on the mating cam guide surface, and roller followers are widely used in cam mechanisms and in linear motions of conveying equipment.
In the part number, V marks the full complement type, UU the sealed type and R the crowned outer ring. The size number is the outer ring diameter in 1/16 inch. Every model on this page is sealed type with a cylindrical outer ring.
Where this product is used

Sizes are in mm with the inch size in brackets. C is the basic dynamic load rating and C0 the basic static load rating.
Selecting the right option
Pick the outside diameter (D, in inches) in the options above. The Model Details give the bore, widths and shaft diameter ranges in mm with the inch size in brackets.
This page is the cylindrical outer ring type. A cylindrical ring has a large contact area with the mating guide surface and suits applications where the applied load is large or the guide surface hardness is low.
Every model here is the full complement type, which is suited to heavy loads at low speed rotations.
Fitting and use
For the sealed type, match the side surface correctly to the mating seating surface given by dimension a in the Model Details and fix it. The mounting part should make even contact with the entire side plate surface: uneven contact may increase rotational torque and shorten the service life.
Keep the oil hole of the inner ring out of the loading zone, which can lead to a short bearing life.
The shaft diameter ranges for push, drive and press fits are in the Model Details for each size.
Lubrication: the models on this page are prepacked with grease.
Track capacity is the load that can be applied continuously on a steel cam guide surface of 40 HRC without deforming or indenting it. For a different hardness it is multiplied by the track capacity factor (0.58 at 30 HRC): ask AIMS if you need the factor for your guide surface.
If you are unsure which size suits your cam track and mounting, send AIMS the part number or the dimensions and we will help you confirm it.
